"You cant have every team south of the Mason Dixon line going broke every year," Cuban wrote.

Whether that's actually true is debatable, because individual NHL franchises don't open their books. Teams like the Phoenix Coyotes, Dallas Stars, Tampa Bay Lightning and Florida Panthers have dealt with financial issues to varying degrees at one time or another. The Nashville Predators and Carolina Hurricanes increased their payrolls leading into the lockout, though the end result is far from determined.

Regardless, Cuban's criticism is a popular one of commissioner Gary Bettman, who was the driving force behind the league's expansion to Southern markets in the 1990s—and Bettman remains a divisive force in labor negotiations.

Cuban made similar remarks earlier this month.

"If you don't fix the problems, they escalate and, well, you see where the NHL is at now," Cuban told CSSNE.com.

"When you have all your southern franchises basically sucking wind, there's a message there that you to fix it," Cuban told the website. "I mean, you have two different worlds; the north and the south. It's kind of like the civil war right now going on, and it's got to be fixed."

Cuban touched on a variety of topics in the Reddit session, including his own business ventures in and outside of pro sports ("i think an MBA is an absolute waste of money"), his reality show "Shark Tank" and his relationship with NBA commissioner David Stern.

One of his points about conflicts of interest between media entities and the leagues they cover: "ESPN pretends to be a journalistic source of information about the NBA, and they are a huge broadcast partner."
